Cross-sections of photonuclear reactions on $^{nat}$Mo targets at end-point bremsstrahlung energy up to $E_{γmax}$ = 100 MeV
Experiments to determine the yields and bremsstrahlung flux-averaged cross-sections <$σ(E_{γmax})$> of photonuclear reactions on the natural Mo targets were performed on the beam from the NSC KIPT electron linear accelerator LUE-40 with the use of the $γ$-activation technique. The bremsstrahlung end-point energies were in the range $E_{γmax}$ = 35...80 MeV. The bremsstrahlung quantum flux was calculated with the program GEANT4.9.2 and, in addition, was monitored using the $^{100}$Mo$(γ,n)^{99}$Mo reaction. Calculations of the yields and average cross-sections <$σ(E_{γmax})$> for photonuclear reactions on stable Mo isotopes were computed using the $σ(E)$ cross-sections from the TALYS1.95 code (for the level density model LD1). A comparison of experimental and calculated cross-sections <$σ(E_{γmax})$> for reactions $^{92}$Mo$(γ,2n)^{90}$Mo and $^{92}$Mo$(γ,pn)^{90}$Nb was performed.
